12 Claims.

This invention relates to slide fasteners of the type covered by Patent1,903,415 of April 4, 1933, in which the slide may be locked in adjustedposition at either side of the fastener.

Special objects of the present invention are to simplify and improve thelocking mechanism and themounting of the same on the slide; also tofacilitate the operation of the locking means and to enable its readyand convenient use as a means for shifting the slide. l

Other objects and the novel features of construction, combinations andrelations of parts by which the objects are attained will appear as thespecification proceeds.

The drawing accompanying and forming part of the specificationillustrates a simple and at present preferred embodiment of theinvention, it being understood that the exact structure may be modifiedand changed all within the true intent and broad scope of the invention.

Fig. 1 in the drawing is a broken front or face view of the fastener;Fig. 2 is a broken central sectional view as on substantially the planeof line 2-2 of Fig. 1; Fig. 3 is a plan view -of the fastener slide andattached handle and locking mechanism.

The inter-engaging securing elements of the fastener are indicated at 5,carried by tapes 6, and adapted to be separated and brought together bythe slide member 7.

A tab or pull 8, is provided for shifting the slide and a specialfeature of this device is that it is swivelly connected with the top oryoked end of the slide by a ball and socket joint, comprising in theillustration, a ball member 9, on the end of the pull confined in a.socket 10, on the slide. The ball member is shown as carried by anangularly extended reduced neck portion 11, at the end of the pull andthe socket is shown as formed in and as constituting in fact, thetransverse yoke 12, connecting the opposite sides 13 of the slide.

The ball socket is shown as notched or slotted at 14, at the oppositesides of the slide to receive and guide the reduced neck portion 11, ofthe pull. In addition to the guiding function, these slots have aretaining effect for holding the pu11 in position overlying theface ofthe slide, at either side of the same. v

The locking of the slide at either side of the fastener is effected inthe illustration, by a single lug or prong 15, shown as bent inward atone edge of the pull in position to pass through guiding and receivingopenings 16, in the opposite sides of the slide into holding engagementwith the stringers, that is, ln the illustration, between adjoiningfastener elements 5.

The broken lines at the left in Fig. 2, show how the pull 8 may -belifted to unlock the slide and the pull then be used as a handle toraise or lower Ct the slide, the swivel connection at such timepermitting any rocking and turning movements of the pull as may be moreconvenient in operating the slide. The dotted lines at the right in thisview indicate how the pull, after being unlocked at one side may beswung around over the top of the slide from one side to the other andthen be turned down over such other side to lock the slide at such otherside of the fastener. The ball socket is shown as having a relativelyWide open beveled mouth 17, at the top, to provide ample clearance forthe neck portion 11, of the pull in these reversingmovements of the pullfrom one side to the opposite side of the fastener.

The passage of the locking lug through openings 16, and engagement ofthe neck portion 11, in notches 14, are sufficient ordinarily for properretention of the pull at the opposite sides of the slide, but to moredefinitely hold the pull overlying the opposite sides of the slide, areleasable 80 detent may be provided, such as the spring tongue shown at18, struck inward from the pull in position to engage beneath the loweredges of the slide at the opposite sides of the same. This singledetent, like the single locking lug, serves for use g5 at both sides ofthe fastener and as both the detent and the locking lug extend inwardlyfrom the face of the pull which is innermost at both sides of thefastener, this leaves the pull with a smooth outer face in position atboth sides of the fastener.

The swivel connection with the yoke portion of the slide centers theapplication of force tothe slide, irrespective of the angle at which thepull is held and prevents any angling or binding action of the slide onthe fastener elements. There are no projecting parts and the structureis particularly neat, compact and small. The ball and socket elementsmay be reversed, that is, the socket be located on the pull and the ballelement be on the yoke of the slide. Other changes in structure may bemade within the true intent of the claims. The angled neck by which theball element is attached to the pull, in effect offsets the pull fromthe ball and socket joint, so that it can lie relatively flat againstthe slide at either side of the same. The socket element is closed overthe ball sufficient to securely hold the ball without restricting toomuch the swivelling action of the pull.

What is claimed is:

1. A slide fastener comprising cooperating fastener elements, a slidefor engaging, and disengaging the same, a pull, a ball and socketconnection between said pull and one end of the slide for enablingrotation of said pull on said end from one side over to the oppositeside of the slide and a single locking lug carried by and projectingfrom one face of said pull in position to engage and interlock withfastener elements at either side of the slide.

2. A slide fastener comprising cooperating fastener elements, a slidefor engaging and disengaging the same, said slide having side portionsconnected by a yoke, a ball socket in said yoke, a pull having a ballelement seated in said ball socket and a single locking lug carried bysaid pull for locking service at either side of the slide.

3. A slide fastener comprising cooperating fastener elements, a slidefor engaging and disengaging the same, a pull, ball and socket elementslocated at one end of said slide and carried by said pull and sliderespectively, whereby the two are swivelly connected, the socket elementhaving notches in the sides of the same faced towards opposite sides ofthe slide and the ball element having a neck portion of a size to entereither of said notches to thereby definitely locate the pull inpredetermined positions at either side of the slide.

4.
